DOOR LOCK DEVICE FOR VEHICLES
To reduce occurrence of sound during switching operation to one time while reducing the driving force of the electric motor, in addition to shortening the switching operation time between the locked state and the unlocked state.SOLUTION: In a door lock device for a vehicle, when an active lever 121 is rotated as driven by an electric motor 131, a bush 160 is in sliding contact with a guide wall 135 while being positioned at the tip part 125a in the guide groove 15 as the worm wheel 133 rotates. When the active lever 121 is rotated without drive of the electric motor 131, with the worm wheel 133 in a stationary state, until the bush 160 in sliding contact with the guide wall 135 passes the apex part 135b, the bush moves in a guide groove 125 from the tip part 125a to the lever support shaft 121a side, against an energized force toward a side opposite to the lever support shaft 121a side. After passing the apex 125b, the bush is moved by the energized force toward the side opposite to the lever support shaft 121a side, in the guide groove 125 toward the tip part 125a and then the bush is held at the tip part 125a.SELECTED DRAWING: Figure 11
【課題】ロック状態とアンロック状態との切り替え作動時間を短くするとともに、電動モータの駆動力を低減しつつ、切り替え作動中に音が発生するタイミングを１回に低減する。【解決手段】電動モータ１３１が駆動してアクティブレバー１２１を回動させる際は、ウォームホイール１３３の回転に伴って、ブッシュ１６０は案内溝１５内の先端部１２５ａに位置しつつ案内壁１３５と摺接する。電動モータ１３１を駆動せずにアクティブレバー１２１を回動させる際は、ウォームホイール１３３が停止した状態で、ブッシュ１６０は案内壁１３５と摺接して頂点部１３５ｂを超えるまでは、レバー支持軸１２１ａ側とは反対側への付勢に抗して、案内溝１２５内を先端部１２５ａからレバー支持軸１２１ａ側に移動し、頂点部１２５ｂを超えてからは、レバー支持軸１２１ａ側とは反対側への付勢によって、案内溝１２５内を先端部１２５ａに向けて移動し、先端部１２５ａで保持される。【選択図】図１１
